SerialNo. 147,442.

This invention relates to new and useful improvements in lens holdersfor trial frames and the like and has particular reference to a metaland composition reinforced holder and method of making the same.

The principal object of the invention is to cover a metallic trial lensholder with a nonmetallic compound to give it the appearance of apractically all composition holder.

Another object of the invention is to form a trial lens holder ofnonmetallic composition down over the lens to secure it in place andtoprovide metallic peripheral teeth to engage.

the ring turning means of a trial frame whereby the ring is turned toaxis.

Another object is to provide simple, durable and economical means forforming a composition trial lens holder of the character stated. f

Other objects and advantages of the invention will become apparent byreference to the following specification taken in connection with theaccompanying drawings, and it will be understood that I may make anymodifications in the specific arrangements of parts, details ofconstruction and methods shown and described within the scope of theappended claims without departing from or exceeding the spirit of theinvention. The preferred forms of the invention only have been shown anddescribed by way of illustration.

In the drawings forming part of this application and wherein likecharacters of reference denote corresponding parts throughout theseveral views:

Figure 1 is a front elevation partly shown in section of a trial lensholder constructed in accordance with the invention;

Figure 2 is a vertical sectional view on line 22 of Figure 1.

Referring more particularly to the drawring 10 has a finger piece orhandle 12 formed thereon to facilitate its positioning in and removalfrom a trial frame and which may be so marked. as at 13, to indicate thepower of the lens inthe holder.- The finger piece or handle 12'may bemade entirely of metal as shown in Figures 1 and 2. I prefer to applythe composition to the metal ring in a plastic or molten condition andto press the same to shape although the composition may be applied assheets or in other ways.

The metallic ring 10 is provided centrally with asuitable flange 14:formed with an annular bead 15 upon which the lens 16 is placed orrested, after which the oppositely outstanding flange portion 14 is spunover as at 17 to firmly position the lens 16 within the ring 10.

In Figures 1 and 2 the lens holderis shown with portions of the metallicring exposed, such as the handle 12 and the toothed edge 18, which isadapted to mesh with and be rotated by a suitable pinion formed in atrial frame, not shown in the drawings. In this'instance the ring 10 isformed with the oppositely grooved faces 19 and 20 and the recesses 21which are adapted to receive the composition or the like 11. Thecomposition or suitable material is pressed into the lens holder duringits plastic state and is then allowed to' dry and harden, after whichits outer faces are highly polished. It will be apparent that during thepressing of the plastic composition or suitable material within the lenshold er it will thoroughly unite within the recesses 21 and therebyrigidly mount itself on the lens holder. p I

Although I have specified the composition as the preferable material itis tobe under-' stood that other materials may be used, such ascellulose compositions or the like.

From the foregoing description it will be seen that I have providedextremely simple trial lens holder with composition or similar material,which may be moulded over, pressed on or adhered to the metallic ring sothat the lens holder will have the appearance of a. composition holderbut Will have the strength of a metallic holder.

Having described my invention, I claim:

1. In a device of the character described, a metallic ring having aprojecting handle portion and a central lens opening with a lens seatannulus" surrounding it, a non-metallic covering on the metallic ringextending from the lens seat annulus to substantially the periphery ofthe circular edge of the ring leaving the projecting handle portion ofthe ring uncovered.

2. In a device of the character described, a metallic ring having aprojecting handle portion and a central lens opening With a lens seatannulus surrounding it, a nonmetallic covering on the metallic ringextending from the lens seat annulus to substantially the periphery ofthe circular edge of the ring leaving the projecting handle portion ofthe ring uncovered, and a lens in the lens seat annulus. i HARRY H.STYLL.
